IC 2177 - Seagull Nebula - SHO Finally back on my NB/BB setup. This target is low in the sky and barely clearing a tree to the south. Good seeing these last few days also helped a lot. IC 2177 is a large nebula that can be found 3,650 light-years away in Monoceros. It is a great target for both broadband and narrowband imaging, and is very close to the much smaller Thor's Helmet Nebula. It is a roughly circular H II region centered on the Be star HD 53367. This nebula was discovered by Welsh amateur astronomer Isaac Roberts and was described by him as, "pretty bright, extremely large, irregularly round, very diffuse." The name Seagull Nebula is sometimes applied by amateur astronomers to this emission region, although it more properly includes the neighboring regions of star clusters, dust clouds and reflection nebulae. Taken with mono narrowband filters and processed in SHO (Hubble Palette). 28 hrs total exposure. Shot from my backyard in Fl in January 2023 using my ES127 telescope, QHY268M camera, and 3nm narrowband filters. Processed in Pixinsight and adquired with NINA.
